Now that we know the San Francisco 49ers selections in this upcoming NFL Draft, we can go through mock draft simulations thanks to the compensatory picks being awarded. I’m using PFF’s Mock Draft simulator. Today, we’re acting as if Jimmy Garoppolo is the quarterback, Trent Williams was re-signed. Still, the Niners weren’t able to retain any other notable unrestricted in-house free agents and are forced to build through the draft.
